The Government Service Insurance System (GSIS; Filipino: Paseguruhan ng mga Naglilingkod sa Pamahalaan) is a government-owned and controlled corporation (GOCC) in the Philippines that serves de jure government employees. Established by Commonwealth Act No. 186 and Republic Act No. 8291 (the GSIS Act of 1997), the GSIS is a social insurance institution that provides a defined benefit scheme. It insures its members against specific contingencies in exchange for monthly premium contributions.
GSIS members are entitled to a range of social security benefits, including life insurance, separation or retirement benefits, and disability benefits.
The GSIS also administers the General Insurance Fund under Republic Act No. 656 (the Property Insurance Law), providing insurance coverage for government assets and properties in which the government holds insurable interests.
Non-government employees, self-employed individuals including those de facto working for the government but not de jure (i.e. "Job Order" (JO), "Contract of Service (CoS)"), and non-working persons are not eligible for GSIS membership. Instead, they could be covered by the Social Security System (SSS). Government employees may also voluntarily enroll in the SSS at their own expense, in addition to their GSIS membership.
